embodies the use 'of a. .plurality of traverse#` guides adapted to 'be reciprocated long-L typedescribecl'in the application for patent;` L i hereinbefore referred to,` tti-1o separate and tudinally ofthe ,windir'1 g. .-1pindle.and'oper-` but' independently of.

One guide operates to lay the materialin place onl theWinding-spindleiA AWhile V.one or more othenguidesfdeposita*` windings of` insulating-material, such as" ings The Wire `is" laid` ina closejwind windings of yarn pr thread intermingle with I 'of the coil. The guide or the insulatingthe wire windings, crossing over and. 'under the latter. at regular intervals, and serve to bind the wire windings in place and'assist Ain insulating one turnfrom another while also providing insulation between the layers material is reciprocated with a quick traverse, wh1le the 'wire-guide has a relatively slow traverse.

` In the accompanying drawings the guide forthe yarn or thread is not illustrated since its arrangementl forms no. part of theV f present invention. It may be driven in any 'suitable manner, and -a convenient 'arrange-- ment is to connect it witha rockable armv lwhich is osci'llated from the cam C. A sec- -ond lcam C2 is employed for reciprocatingl the wire-guide F and the means for connecting it thereto are'shown in Figs. 1 and 3. The cam. C2 is mounted free to rotate on the am-shaft C, independently thereof., and isdriven from-a separate means as later deL scribed. vReaching in from.'the side of 'the frame A is av bracket A, see Figs. 1 and 3,

- supporting .a pivot stud .g on which is mounted a rockable arm o r lever G. Thev lever Gr is arranged adjacent the periphery of .thecam .C2 landcari'ies a roll or-stud gat its lower end which is adaptedto engage.

" with the cam-gr`oove` c. --The upper portion .wlii'chis secured a 'slidable member h held' of the'flever G is formed witlra slotg2 l1n in' place by the bolt 71,. Pivotally connected tothe member tat one end is a link or connesting-rod H,the opposite end of whichis .pivotally ,secured toa terminal member 71.2.'

The member h2 is 'adapted to'be adjusted up and down in a'slo't i of a vertical arm I. The arm I serves as a cross-head adapted to slide on two parallelhorizontal rods j, j

lwhich vare held inl suitable supporting arms J, J', .Also .arranged to slide on the rod j lis an armV K having its lower end secured to a sleeve k on which'ismounted the bearing i of the arm I. AThe .arm K` carries a bracket K. at its upperfend on whichare .provided bearings for-two rotatable guide! wheels or pulleys c, 7a2. 'The' wiref'wI or other` material being wound leads from its source of supply, not here shown, down under-the pulley Zu and thence over and partlyaround the -grooved periphery ,of the guidei wheel lo?, whence it is'delivered to the windacts through the roll, gf-to rock. the lever G ing-spindle B. Rotation of the cam C2 and this motion is transmitted through the .back and-.forth on the rods y', j. The traverseguide arm K being connected t9 the arm I at its base is. therefore .caused tov traverse back and forth along the windingspindle B to lay the turnsfof-the winding in placein theusual' manner. The length of traverse of the guide is determined by the operative length of the lever G and this may be varied as required 'by adjusting; the

connecting-membersat the ends of the rod H upor down in the slots'g2 and i. The.4

guide for the yarn' orother insulating-material may be connected to be drivenfromthe camC -in subs ntially the same manner. v.as above describe and in this way the length of traverse ofboth guides can. be altered as required withoutthe need .of sub- As before mentioned, the, cam C2 is rotated through means independent ofthe cam# shaft C which drives the cam C', and, since the rotationof the cam C2 is at a relatively slow speed, a-convenientmeans for driving it is'through Vthe use of worm gearing.

WithV such arrangements-it "isiiin rpracticable to control the winding-mecha nsm So as to stop the guide at the completion of' any one layer of winding andtherefore the machine Will almost invariably stop with the guide'some distance away from the end of .the coil. New, in order to properly secure the free endof the Wire to the end of the finished coil, so that'it can be used asa lead, it is usual t Wind it about the ;!1

coil with a few extra turns, thereby brin ing it tothe point Whereit is to be fastene by solder. Heretofore Ait has been necessary to perform this operation .of winding the Wire out to the-end of the coil by hand, after l'the coil has been taken off the Windingvspindle or arbor. l With my present improvement the operation maybe accomi v plished on the vmachine before the coil is Ulatter through vthe crank.

This serves .to carrythe guide F .along the spindle B t0 inish its traverse. in thel direction-in which it'was last mov- 'ing, and in themeantimethe winding-spin-V .much'fs l .hair .For this reasongitwould require too 50, 110mg a time to dependen the manual rota-y rjemoved therefrom and' hence the wor-k can be done'k much more conveniently and expeditiously.
